To'aZZ 'whom it may concern: j

Be it known that T,llnivn'iin llhmdan,

' a citizen otl the? 4United States, residing` at 'New Yorkcity.. in thecounty` ot New -York andState' of New York,l have invented eertaln nei'and useful'linproveineiits in llxpansible Mechanism `for[1)ainper-Regulators,

` ot' which the following is a speeitication.

The invention relates to improvements in expansible ineehaiiisinfforftliiid heating danip'er regulator apparatus and'has -par-A tieularreference to that ty'ietof`:eXpansihle mechanism consisting,` ot' aeo'n'voliitetlv sheety inetal pipe havingi'ornied therewith'a. dependingchamber adaptedlto'iin "L a de-- pending' bulb or chamber siibi'iierl `d,in the line'ot the fluid circulation ot a Huid heat` inf; generatoi.'tor receiving the initial forces' ot said fluids under pressure 'to actii'poi damper controlling"means.

A further objectl ot 'the` invention. iwsthei providing ot a secondarye'xpan: `e`. means' comprising a coin'oliited 'pipe'o't a resilientmaterial such as a molded form provided with a predeterminedfnumber of"convolutions ot hard rubber orot al similar sub` stance adapted'to actin connection with `a primary expansible means preferably of the wellknown type ot" metallic expansible Structure.

=What l claim: dadesire to secureby Letters Patent-otl tlicUhited Statesis:--

1.`- A device ot the character described comprising a damper regulatorsupporting easing' having' formed therein a fiuid chamber and tluid pipereception means, an ex? egulator controllingV pansible mechanismreception chamber depending in .said fluid chamber formed in saidAcasing, a pipe adapted for expansion having formed on its lower end asupporting base adapted to engage said reception chamber in said. casingand vhaving its upper body portion formed into a plurality ofconvolutions, a cap having cast integrally therewit-h an actuating pinadapted to engage the a supporting base and inits upper body por-`extreme upper convolution in said pipe, and a hood surrounding sa1dexpansible pipe provided with an aperture adapted to receive the pin onsaid cap.

2. A device of the character described including an expansible pipe fordamper regulators having formed on its lower closed end yactuating pin,a hood engaging said casing and adapted to `surround the convolutedportion of said expansible pipe, the lower closed end vof saidexpansible lpipe being so arranged with relation to the receptionchamber as to form a supporting base or wall for chamber the upperconvoluted portion of said piper 3. A device of the character described,comprising an expansible tube, a fluid cham ber' with fluid pipereception means, a chamberprojecting into said fluid chambersubstantially as set forth, and provided with a closed Wall interposedbetween the iiuid and theiiiterior of the chamber` projecting into thelfluid chamber, whereby itlwill be surrounded and acted upon by thefluid-entering the fluid chamber, a hollow extension projecting from theexpansible tube and entering and fitting closely within the chamberprojecting into the fluid chamber, but removable therefrom as described,without opening the pipe or its chamber, and means connected with saidexpansible tube for operating/a regulating device, all substantially asset forth. i

4. A device of the character described,

comprising ail expansible tube, a fluid chamber with iuid pipe receptionmeans, a chamber projecting into said fluid chamber substantially yasset forth, and provided with a elosedgwall interposed between the fluidchamber and the interior of the chamber projecting intothe fluidchamber, whereby itwill be surrounded and acted upon by the fluidentering thefluid chamber, a hollow extension projecting from theexpansible tube and entering and fitting closely within the chamberprojecting into the fluid chamber, but1 removable therefrom, asdescribed, without opening the pipe or its chamber, a cap closing theouter end of the cxpansiblc tube and provided with a pin extendingtherefrom all substantially as set forth.

5. A device of the character described, comprising an expansible tube, afluid cham# ber with fluid pipe reception means, a chamber projectinginto said fluid chamber substantially as set forth, and provided with aclosedl wall interposed between the :lluid chamber and the inteiior of't-he chamber projecting into the fluid chamber, whereby it will besurrounded and acted upon by the fluid enteringthe fluid chamber, ahollow extension projecting from the expansible tube and entering,andfitting closely within the chamber projecting into the fluid chan'i-vber, but removable therefrom, described, without opening the pipe or itschamber, a cap closing the outer end of the A exj'iansible tube andprovided with a pin extending -therefrom, and a casing apertured for thcpassage of said pin, and surrounding said expansible tube allsubstantially as set forth. 6. A fluid conveying pipe, provided with afluid chamber therein, closed at the sides, a

`chamber projecting into said fluid pipe chamber substantially as setforth, and provided with a closed wall interposed between the fluid.chamber and the interionof the chamber projecting into the fluidchamber, whereby it will be surrounded and acted upon by the fluidentering the fluid chamber, an expansible tube, a hollow extensionprojecting. from the expansible tube and entering and fitting closelywithin the chamber projecting into the fluid chamber, but removabletherefroin' described, without opening the pipe or its chamber, andmeans connected with said expansiblc tube for op erating a regulatingdevice, all substantially as set forth. v
